Red List Candidates:<br />
(please refer to Appendix 1 <strong>for</strong> details on EOO and AOO).<br />
In September 2003, exhaustive literature searches at Kew (e.g. in Açevedo-Rodriguez,<br />
Oldfield etc.) and thorough investigation and careful interpretation of <strong>the</strong> IUCN<br />
guidelines, resulted in <strong>the</strong> identification of 35 additional Candidate Red List taxa,<br />
bringing <strong>the</strong> total to 44 putative threatened taxa. Of <strong>the</strong>se candidates, 3 are assessed<br />
here as Critically Endangered (CR), 10 as Endangered (EN) and 22 as Vulnerable<br />
(VU). Many of <strong>the</strong>se are Puerto Rican bank (PRB) endemics whose Extent of<br />
Ocurrence (EOO) cannot be more than 20,000 km 2 as <strong>the</strong> maximum EOO <strong>for</strong> this<br />
biogeographic unit (calculated using GIS) is c. 9,570 km 2 . The maximum EOO <strong>for</strong><br />
<strong>Virgin</strong> Island endemics is 810 km 2 . A summary of selected PRB island areas follows<br />
